A square has both parallel sides
being the top and bottom
but also both the sides
AND so does a PARALLELogram
BUT a square has ALL right (90 d) angles
and a parallelogram does NOT
ALSO . . . . . SUMMARY . . . . .
The sides of a square are parallel
and all the angles equal 360 degrees,
so it's a parallelogram. BUT a
parallelogram is NOT a square
because a squares angles need to be 90 degrees.
does that answer your question?
Answer:
5.25 hours
Step-by-step explanation:
One week = 7 days
7 x 0.75 = 5.25 Hours
Hope this helps, mark as brainliest :)
Angle 1 is a vertical angle with 6
These statements are true:

This is <em>true</em> because of the definition of a rhombus which states that opposite sides are parallel.


This is <em>true </em>because the diagonals of a rhombus bisect each other at right angles.

This is<em> true</em> because the four sides of a rhombus are all equals.

This is also <em>true</em>. Two angles are
supplementary when they add up to 180 degrees. Angles in rhombus are equal two to two. Let's name:
Then it is true that:

Besides, a rhombus is a quadrilateral and it is true that the interior angles of a quadrilateral add up to 360 degrees, thus:
